Abstract: POWER GAS BURNER     ABSTRACT OF THE DISCLOSURE          A power gas burner of the gun type.  The burner embodies an air tube that is mounted on the appliance with which the burner is to be used.  Primary and secondary air is supplied to the air tube by a blower of the turbo-compressor type that is driven by a motor through an adjustable speed drive.  Fuel gas is supplied to the air tube through an eductor tube.  Gas is supplied to the eductor at regulated pressure through a metering orifice.  The discharge end of the eductor is open and is located on the axis of the air tube and in the throat of a venturi that is also mounted on the axis of the air tube.  Air supplied by the blower flows at high velocity through the throat of the venturi on the exterior of the eductor, resulting in a reduction in pressure in the venturi at the discharge end of the eductor.  This primary air is mixed in the venturi with gas discharged from the eductor.  A flame retention burner head is disposed at the discharge end of the air tube and the mixture of primary air and gas is discharged through the center of the burner head.  Secondary air flows around the venturi in the air tube and is discharged through the outer portions of the burner head.  A spark igniter is provided for igniting the primary air-fuel mixture near the burner head.  The flame propagates outwardly, mixing with the secondary air downstream of the burner head,

Abstract: Case 232S     ABSTRACT OF THE DISCLOSURE          A valve seat structure for an expanding type gate valve.  A valve seat is received in each annular seat recess formed around the upstream and downstream flow passages and opening to the valve chamber wherein a gate assembly is movable between open  and closed positions.  An annular face seal is mounted within an annular groove in the front seat face of each valve seat.  A substantial portion of the bottom of the annular groove comprises a frusto-conical bottom portion which forms a wedging surface with a cone angle in the range of approximately 30° to 60° and disposed substantially coaxial with the groove sides and the flow passages.  The rear seal face of the face seal has a frusto-conical rear portion that conforms to the frusto-conical bottom portion.  The annular groove is wider than the thickness of the face seal so that the face seal loosely fits within the annular groove.  The front seal face extends beyond the front seat face a dis-tance in the range between approximately .0051 cm and .0381 cm when loosely seated in the annular groove.  When the gate assembly is expanded to the open or closed positions, the front seal face engages the gate assembly and the annular face seal is axially compressed to effect a seal.           In the closed position, fluid pressure in the upstream flow passage causes the annular seal to wedge against the frusto-conical bottom portion towards the gate assembly whereby the sealing relationship between the annu-lar face seal with the gate assembly and frusto-conical bottom portion increases with increasing fluid pressure.  When the gate assembly moves to the collapsed condition, the up-stream annular face seal moves toward the gate assembly and as fluid pressure equalizes on both sides of the face seal effects a wiping relationship with the gate assembly without causing back wedging thereof.

Title: Pilot driver for plasma display device
Inventor: STROM RICHARD A
IPC: G09G3/288
Filed: 1981-10-06
Granted: 1984-04-10
Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a pilot cell driver for a capacitive memory plasma display device having three output states:  high, low, and floating.  The floating state of the pilot cell driver is used in combination with a feedback of the plasma display panel sustain voltage to create a third voltage level on the pilot cell drive line for use in rewriting the pilot cells.  The pilot cell driver is comprised of a pull-up switch and pull-down switch.  After the pull-up switch is activated for a short period of time, the output of the pilot cell driver relaxes to the floating state.  The floating state voltage is achieved, for example, on a vertically oriented pilot cell drive line by coupling to a horizontal sustain drive voltage which switches from the pull-up voltage to the pull-down voltage during the relaxation time of the pilot cell driver.          By capacitively coupling the horizontal sustain voltage to the vertical pilot cell drive electrode, the floating state voltage is achieved.

Abstract: SPLIT MASTER LINK FOR TRACK  OF TRACK-LAYING TRACTORS              Abstract of the Disclosure A split master link includes first and second separable sections which are joined together at an overlapping joint com-prising a series of interengaged teeth located centrally in the link mass.  The link sections have confronting surfaces forming continuations of the opposite ends of the tooth racks of the sections and in one embodiment, one of each set of confronting surfaces at an end of the tooth racks is stepped so that a relief area extends from the tooth rack towards a side of the link through a distance of approximately three-fourths of the dis-tance of the tooth to the side of the link.  In a second em-bodiment, the pair of confronting surfaces at each end of the tooth racks are arranged in converging relationship so that they converge at a side of the track link.  A relief area is thus formed at the opposite ends of the tooth racks and each relief area extends to an adjacent side of the link.  Relief areas of both the embodiments serve to greatly decrease the cyclic strain that the track link would experience for a given load as com-pared to a track link having no such relief areas.

Abstract: ABSTRACT OF THE DISCLOSURE         A mechanical thruster for positively separating two releasably joined components under a controlled time delay.  The thruster is particularly useful for mechanically opening canisters containing survival kits as they are being dropped from an airplane to a target.  The thruster comprises an adjustable mechanical timing means which is actuated when a pin is pulled from it.  After a predetermined time delay, the timing means actuates a plunger mechanically associated with it, which plunger dislodges a locking piston.  This locking piston in locking position mechanically holds a thruster body about a barrel of the device.  Once the locking piston is displaced, the thruster body is propelled away from the barrel.          When the mechanical thruster is secured to the main body of a container, and the thruster body is attached to the container lid, separation of the thruster body from the rest of the thruster causes the container lid to separate from the container, making it possible for the container contents to be removed from the container.  The device according to the present invention can be used in place of known, pyrotechnic thruster devices.
